A 市火车站女播音员声调优雅沉着地播送着113 次列车就要进站的消息。 113 次列车是专门为黑龙江生产建设兵团的四十余万知青大返城临时增加的车次。A 市是运行中的第一大站，这里已经有一千七百多名几天前抵达A 市的知青正期待着转乘知青"专列"兼程南下。站前有几千名接站的人。当113 次列车终于疲惫地驶进站台时，车窗口早已塞满了伸长脖子张望的脑袋，他们大声咒骂着为什么不放进接站的人。最后一个走下列车的叫姚玉慧，几天前，她还在兵团担任教导员的职务。这时广播里传来有车接她的消息。（A female announcer in the railway station of A City is broadcasting the message with a graceful and calm tone that Train No. 113 is coming. Train No. 113 is specially added for over 400 thousand educated youths of Heilongjiang Production and Construction Corps to return to the city. The railway station of A City is the largest station in operation. There are more than 1700 educated youths who arrived at A City a few days ago waiting to go south by transfer to the "special trains" for educated youths. Several thousand people are at the station to pick up them. When Train No. 113 finally steams into the station tiredly, heads looking around fill the train windows and they are shouting loudly why not let the people who pick them up in. The last person getting off the train names Yao Yuhui who served the post of instructor in the corps several days ago. Then comes the message that someone is picking her up by car.）
